- Strong coupling constants of heavy baryons with light mesons in QCD. Aliev, T. M.; Azizi, K.; Savci, M. // AIP Conference Proceedings;Oct2012, Vol. 1492 Issue 1, p146
The strong coupling constants of the heavy spin-1/2 and spin-3/2 baryons with light pseudoscalar and vector mesons are calculated in the framework of the light cone QCD sum rules. Using the symmetry arguments, some structure independent relations among different correlation functions are...

- Magnetic Moments of 70-Plet Baryons in Quark Model and QCD Sum Rules. Aliev, T. M.; Zamiralov, V. S. // Advances in High Energy Physics;10/12/2015, Vol. 2015, p1
Magnetic moments of the positive parity 70-plet baryons are estimated in the framework of the nonrelativistic quark model and QCD sum rules method. It is found that the magnetic moments of the 70-plet baryons can be expressed in terms of the F and D couplings and exhibit unitary symmetry. The...

- Beauty Vector Meson Decay Constants from QCD Sum Rules. Lucha, Wolfgang; Melikhov, Dmitri; Simula, Silvano // AIP Conference Proceedings;2016, Vol. 1701, p050007-1
We present the outcomes of a very recent investigation of the decay constants of nonstrange and strange heavy-light beauty vector mesons, with special emphasis on the ratio of any such decay constant to the decay constant of the corresponding pseudoscalar meson, by means of Borel-transformed QCD...

- Axial anomaly and vector meson dominance model. Klopot, Ya.; Oganesian, A.; Teryaev, O. // JETP Letters;Aug2014, Vol. 99 Issue 12, p679
A connection between the axial anomaly and the vector meson dominance model is revealed for the processes of pseudoscalar meson-photon transitions. The analytic continuation of the anomaly sum rules, which are exact QCD relations following follow from the dispersive representation of the axial...

The strong coupling constant $$g_{h_{b}B_{c}^\mathrm{PS}B_{c}^\mathrm{V}}$$ is calculated using the three-point QCD sum-rule method. We use correlation functions to obtain these strong coupling constants with contributions of both $$B_{c}^\mathrm{PS}$$ and $$B_{c}^\mathrm{V}$$ mesons as...

In this work, we use the QCD Sum Rules (QCDSR) technique to obtain informations about the strong coupling constant of the three meson vertex [lowercase_phi_synonym]DsDs. The calculation is done for the case where the [lowercase_phi_synonym] meson is considered off-shell.

- A Bayesian analysis of QCD sum rules. Gubler, Philipp; Oka, Makoto // AIP Conference Proceedings;5/23/2011, Vol. 1343 Issue 1, p343
A new technique has recently been developed, in which the Maximum Entropy Method is used to analyze QCD sum rules. This approach has the virtue of being able to directly generate the spectral function of a given operator, without the need of making an assumption about its specific functional...

- Restrictions on Exact Current Correlation Functions and Reliability of Sum-Rule Results. Pivovarov, A. A.; Zubov, A. S. // Physics of Atomic Nuclei;Sep2000, Vol. 63 Issue 9, p1650
Criteria of reliability are studied for results obtained within the sum-rule approach in QCD and in some toy models. The criterion of validity of the approximation for current correlation functions based on operator-product expansion within Borel sum rules, suggested previously in the...

- Form factor of the B meson off-shell for the vertex Bs*BK. Cerqueira, A.; Bracco, M. E. // AIP Conference Proceedings;11/12/2010, Vol. 1296 Issue 1, p298
In this work we evaluate the coupling constant and the form factor for the vertex Bs*BK using the QCD Sum Rules. In this case we consider the B meson off shell. The only theoretical evaluation for the coupling constant was made using the Heavy Hadron Chiral Perturbation Theory (HHChPT) and we...
